Also, these F-R rates are very similar to the rates that came with a different e9x M3 high-end setup that most owners on ths forum had issues with, especially when used on the track with a 0.75"+ drop.

Please don't read this post the wrong way - the Ohlins DFV dampers are awesome - but these rates seem way too soft for a street, or dual-purpose, setup on the e9x M3. Also, glad to see another great suspension option almost on the market for the M3

weight distribution is 63/37 on a mini, might have something to do with it

The wheel rate of the R56 Mini kit also is similar to the e9x M3 rear wheel rate - I don't know the rear motion ratio of the R56 Mini because it's a coilover rear. Also, the Mini weighs ~800-900 lb fewer than the e9x M3 with a much shorter wheelbase.

I didn't want to list the name of the other damper but it's a DA damper made by a direct race competitor of Ohlins. Having used 380/620, 600/800, 400/600, 400/672, and 500/800 rates on the e92 M3 with Moton, TCK, and JRZ dampers I still strongly believe ~350/~685 is a street-biased setup even on the Ohlins DFV. Just like on the Mini kit if you want to swap rates you have to buy four additional springs...

After all it is a Road & Track kit, not their Motorsport or PSI Raceline kit. 6kg and 12kg springs will be fine for a street cars that sees a few track days a year.

On the 135/335 kit about 50% of the people upgrade their springs to Swift and the other 50% love the kit out of the box, it may just come down to what the preference of each driver.

Sounds good. Knowing how well the R&T kit performs on my R56 as well as the wide range of rebound damping adjustment, the R&T e9x kit should be awesome on the street and very capable of handling much higher rates for people that want to more frequently track their car
